We are running a Windows SBS 2003 environment; I came in on Wednesday and everything worked great. I installed some basic updates via WSUS and left, now at that ponit everything still worked great.
The issue started Thursday morning; all connectivity is up and running smoothly. Nearly, 75% of the webpages we attempt to browse to just time out after waiting. Google works fine, but no other we page seems to work. When I plugged my laptop directly into the router providing network to the LAN, every Internet site worked great and came up fast.
The sole server has two NICs, one providing internal private IP addresses for comms, and the 2nd that routes out to Qwest which we pay for.
I looked at log files, I looked at IP settings, I look everywhere and can't find any type of solution for this issue. Google seems to work great, but nothing else does - network traffic works great internally, but externally it does not.
